Product Description

Product Description

Carbon steel pipes are divided into two types: hot-rolled and cold-rolled (drawn) steel pipes.

Hot-rolled carbon steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.

In addition to general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, and other steel pipes, cold-rolled (dial) carbon steel pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, Rust thin-walled steel pipes, special-shaped steel pipes.

what is carbon steel:
Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. Also called carbon steel. Generally also contain a small amount of silicon, manganese, sulfur, phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness and the higher the strength, but the lower the plasticity. According to the quality of steel, carbon steel can be divided into ordinary carbon steel (higher phosphorus and sulfur), high-quality carbon steel (lower phosphorus and sulfur), high-grade high-quality steel (lower phosphorus and sulfur) and special grade High quality steel. According to the carbon content, carbon steel can be divided into low carbon steel (WC 0.25%), medium steel (WC0.25%-0.6%) and high carbon steel (WC>0.6%). Generally used for engineering structures and general mechanical parts. For example, Q235 can be used to make bolts, nuts, pins, hooks, and less important mechanical parts, as well as rebar, section steel, and steel bars in building structures. 316 stainless steel is a kind of austenitic stainless steel. Due to the addition of Mo element, its corrosion resistance and high temperature strength are greatly improved. The high temperature resistance can reach 1200-1300 degrees, and it can be used under harsh conditions. Carbon steel does not corrode more than 316 stainless steel.

The difference between carbon steel pipe and seamless steel pipe:
1,Seamless steel pipe is a steel pipe without weld seams manufactured by piercing and hot rolling. Sometimes it is necessary to further cold-work the hot-worked pipe in order to obtain the corresponding shape and size.
Carbon steel pipes are generally made into round, square, flat and other shapes through multi-rolling.

2,Seamless steel pipe is the most widely used pipe in petrochemical production equipment today.
Carbon steel pipes are more widely used. At the same time, the main requirement of carbon steel pipe is its chemical composition is the carbon content.
Seamless steel pipe is the largest type, referring to seamless steel pipes with a wide range.
